As helpless as you might feel scrolling through all the stuff it knows, the archive is an excellent starting point for anyone who is curious about what information you give, knowingly and unwittingly, to Facebook and potentially other companies too.

What information does Facebook keep about you?

In short, virtually everything. In a table on its site, Facebook shows you what information it keeps, and where you can find it. Some of it is public, like your vanity URL, and some of it you can only see in the data archive for you. The complete list is here.

1. All your contact info…

Once you download Facebook onto your phone and permit it to see your contact list, it scrapes all the numbers, addresses, and emails from your contact list. Even those who don’t have Facebook have their details harvested because of those who do.

So i also tried downloading my facebook zip file.I was shocked that facebook has my contact information, my call logs and my text activities. this is a serious breach of data privacy and security.@Salomelugardpic.twitter.com/pRl7bAHVBP

The list shouldn’t come as so much of a surprise, as you do have to opt in to allow Facebook to access your contact info. Even so, the sheer size of the list as you scroll down is eye-opening—when was the last time you saw the phone numbers of all your friends and family?

2. … and all your calls and messages

In addition to your contact information, you’ll also find every message you’ve written on Messenger.

Every. Single. One.

Click on a name and revisit those old cringey messages from seven years ago (or the newer and probably no less cringey ones) and you’ll realize how Facebook can target ads well enough to convince many people into thinking it eavesdrops on conversations.

You won’t see your deleted messages on here, but as a recent tweet from Max Schrems (a lawyer and privacy activist who has been fighting Facebook on privacy issues since he was a student) shows, it may merely be choosing not to include that in your downloaded archive.

3. All uploaded photos, and their metadata

All the photos you’ve ever uploaded onto Facebook are available to view in their separate albums, complete with comments and a trove of metadata.

From this information, Facebook knows what camera you used, what exposure and ISO speed you used, where you took the photo, and from where you uploaded it. From your photos, Facebook knows where you took them, and therefore where you were and, depending on how often you take and upload photos, how long you were there for.

One thing you don’t see are the photos you’ve deleted after users pressured Facebook into removing deleted photos from its servers in 2012. But as we saw from Max Schrem’s tweet, it may well still have them but just chose not to include them in your downloaded archive.

4. All your faces

With every photo uploaded with your face on it, Facebook’s rather ominously named DeepFace technology can identify you with 97.35% accuracy. Deepface performs better than the FBI’s facial recognition technology, which has a still-impressive 85% accuracy.

Can we talk about how weird the "Facial Recognition Data" section of your Facebook data archive is? Like what even is this and how could it ever be useful? (values changed to protect my face) pic.twitter.com/nV6jGRXZdZ

The technology Facebook uses bases its facial recognition on pictures you’re tagged in. According to the research group behind the technology, it employs more than 120 million parameters to determine whose face is whose.

If you live in the European Union, you may find this section missing as an EU data protection law (which is getting an update pretty soon) bans the technology. But incredibly, amidst this data scandal, Facebook has started asking some of its European users to consent to facial recognition technology without giving a clear option to opt out.

5. All your log-in sessions

Every time you log in, or open Facebook, Facebook records the time, date, IP address, and browser or app you’re using.

From this information, it can determine where you are during the day—from your daily commutes to where you go on holidays. It can pinpoint the exact time and place you log in to Facebook, and, depending on how often you use Facebook, it could map out your whole life.

6. The advertisers who have your contact info

Perhaps the most amusing part of the archive is the ad section, which lists all the advertisers that have your contact information, the ads you clicked on while on the site, and the topics in which Facebook thinks you have the most interest.

Anything you may have liked, shared, or clicked on, either on Facebook or on a website that has Facebook cookies on it, are all used to get a better idea of what ads you would more likely click.

Facebook has been able to make its money by providing corporations and state actors a two-billion-strong user group from which to select its target market.

Collecting data from its users is the keystone of Facebook’s business model, and It’s unlikely to stop anytime soon.

It’s not just Facebook that stores your data

Corporations around the world are breathing a small sigh of relief that it’s Facebook and not them that are in the center of this colossal privacy storm. Lest we forget Equifax, which suffered a horrendous data breach that exposed over 150 million customers to identity theft. And let’s not get started on Google (you can download all your data there too if you like).

Facebook also owns WhatsApp and Instagram and, with the introduction of even more apps made to harvest data, it’s clear that Facebook is diversifying the ways it collects user (and non-user) data en masse.

If you’re going to cut the head off this digital hydra and delete your Facebook, expect it to find new ways of getting your data. Stay sharp and check who owns the apps and avoid companies that ask for your personal information. Look for alternatives that don’t bombard you with targeted ads and wean off your reliance on Facebook.

At large, be wary of online services that you use for free. As the saying goes: “If you’re not paying for the product, you are the product.” If you have to use them, disinformation always helps. A different name, birthday, and email address can help shield your online social identity.

Microsoft, not so much. I mean they have all my data but it does not feel creepy. They even publish statistics of how many data requests they turned over to the authorities in a given semester, bifurcated according to geography. Barely in the hundreds which feels comforting. Microsoft has also fought US legal courts on turning over email contents to criminal prosecutors.

Google and Facebook have no such respect for data integrity.

I have boycotted Facebook for a very long time. I still check it sometimes to befriend/unfriend some people.

Thank God for Express VPN. Now these big corporations don’t follow me around like a sniffer dog.
